WinList() don't work

[XGamerGuide]

I'm trying to call WinList() with a handle. That should be possible:

Quote

The title/hWnd/class of the windows to get the list.

But I only get back an 2d array that looks like this:

---------
0 |

(That means no window was found.)

It's not the window or the handle. When I call other functions like WinExists() or WinGetHandle() it works.

Is it because of me, the description in the reference or because of Autoit who makes a mistake?

No, because of the rest of my program I don't want to use WinGetTitle() because the format of WinList() has to be kept. Alternatively, I could create a 2d array myself, but it should also work with WinList() ... I hope.

Tested a bit, and it appears that it returns an empty array ...

Anyway, WinList returns an array of Title and hWnd. As an hwnd is unique, if you already know it, why do you need WinList ?

Logically, passing an hwnd to WinList should return an array with only 1 entry ...

I don't get the logic behind that statement ...

func _WinList($arg, $text = '')
    if IsPtr($arg) or IsNumber($arg) then
        local $res = WinGetTitle($arg,$text)
        if $res == '' then
            local $ret = [[0,0]]
            return $ret
        endif
        local $ret = [[1,0],[$res,ptr($arg)]]
        return $ret
    endif
    return WinList($arg,$text)
endfunc

My program is designed to process the output from a WinList() function. But there is an event in my program where the handle is used instead of the title. Of course I can also write my own function like you wrote one, but I was hoping that it would work without it.

if $res == '' then

Besides, I think the title can also be empty:

#include <Array.au3>
_ArrayDisplay(WinList())

WinGetTitle

Return Value

Success:	a string containing the complete window title.
Failure:	"" if the window is not found.

But you're right in the sense of a window can have an empty title, was lazy, anyway just use GetWindowText ...

anyway just use GetWindowText

The text can also be empty. For this you also have to use WinExists() to check whether the window exists.

[636C65616E]

GetWindowTextA and GetWindowTextW

The result only tells you if it fails or not, this is not about the text itself

Just use the WinAPI : _WinAPI_GetWindowText

EDIT1:

Quote

If the window has no title bar or text, if the title bar is empty, or if the window or control handle is invalid, the return value is zero

Well, yeah check if the window exists, I'm really starting to be tired :/

EDIT2: nop

$form = GUICreate('')
$res = _WinAPI_GetWindowText($form)
ConsoleWrite(_WinAPI_GetLastError() & ': ' & _WinAPI_GetLastErrorMessage() & @CRLF)
ConsoleWrite('title: "' & $res & '"' & @CRLF)
GUIDelete($form)
$res = _WinAPI_GetWindowText(0)
ConsoleWrite(_WinAPI_GetLastError() & ': ' & _WinAPI_GetLastErrorMessage() & @CRLF)
ConsoleWrite('title: "' & $res & '"' & @CRLF)

just check the last error

That's all you need for it:

If WinExists($p) Then
    $ret = WinGetTitle($p)
EndIf

I can manage my own function that turns it into a 2d array, but my question was why it doesn't work with WinList(), although it should actually work.

I was digin a bit, but as it is agains EULA to reverse I will not explore futher.

But as far as I've seen (without breaking the EULA) it may be an internal bug.
